### Run Example via Cargo

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Execute a specific example using the cargo CLI with the async feature enabled.

```bash
cargo run --example signup_consumer --features async
```

--------------------------------

### Install Taplo CLI

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/taplo/README.md

Commands to install the Taplo CLI globally using different package managers.

```bash
cargo install taplo-cli --locked
```

```bash
yarn global add @taplo/cli
```

```bash
npm install -g @taplo/cli
```

--------------------------------

### Initialize and use RainClient synchronously

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Demonstrates setting up the RainClient and performing a blocking user application initiation.

```rust
use rain_sdk::{RainClient, Config, Environment, AuthConfig};
use rain_sdk::models::applications::InitiateUserApplicationRequest;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = Config::new(Environment::Dev);
    let auth = AuthConfig::with_api_key("your-api-key".to_string());
    let client = RainClient::new(config, auth)?;

    let request = InitiateUserApplicationRequest {
        first_name: "John".to_string(),
        last_name: "Doe".to_string(),
        email: "john@example.com".to_string(),
        wallet_address: None,
    };

    let application = client.initiate_user_application_blocking(&request)?;
    println!("Application ID: {}", application.id);

    Ok(())
}
```

--------------------------------

### Initialize and use RainClient asynchronously

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Demonstrates setting up the RainClient with an API key and performing an asynchronous user application initiation.

```rust
use rain_sdk::{RainClient, Config, Environment, AuthConfig};
use rain_sdk::models::applications::InitiateUserApplicationRequest;
use uuid::Uuid;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create configuration for dev environment
    let config = Config::new(Environment::Dev);

    // Create authentication config with API key
    let auth = AuthConfig::with_api_key("your-api-key".to_string());

    // Create the client
    let client = RainClient::new(config, auth)?;

    // Initiate a user application
    let request = InitiateUserApplicationRequest {
        first_name: "John".to_string(),
        last_name: "Doe".to_string(),
        email: "john@example.com".to_string(),
        wallet_address: None,
    };

    let application = client.initiate_user_application(&request).await?;
    println!("Application ID: {}", application.id);

    Ok(())
}
```

--------------------------------

### Configure SDK Environment

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Select between development, production, or custom API endpoints.

```rust
// Dev (default)
let config = Config::new(Environment::Dev);

// Production
let config = Config::new(Environment::Production);

// Custom URL
let config = Config::new(Environment::Custom(
    url::Url::parse("https://api.custom.com/v1")?
));
```

--------------------------------

### Authenticate with API Key

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Initialize the authentication configuration using an API key.

```rust
let auth = AuthConfig::with_api_key("your-api-key".to_string());
```

--------------------------------

### Apply Custom Configuration

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Customize SDK behavior by setting timeouts, user agents, and logging preferences.

```rust
let config = Config::new(Environment::Dev)
    .with_timeout(60)  // 60 second timeout
    .with_user_agent("my-app/1.0".to_string())
    .with_logging(true);
```

--------------------------------

### Configure Cargo dependencies

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Add the required features to your Cargo.toml file based on whether you need async or sync operations.

```toml
[dependencies]
rain-sdk = { version = "0.1.0", features = ["async"] }
```

```toml
[dependencies]
rain-sdk = { version = "0.1.0", features = ["sync"] }
```

--------------------------------

### Format and Check TOML Files

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/taplo/README.md

Commands to check formatting or apply automatic formatting to TOML files using a configuration file.

```bash
npx @taplo/cli fmt --config taplo.toml --check
```

```bash
npx @taplo/cli fmt --config taplo.toml
```

--------------------------------

### Handle API Errors

Source: https://github.com/yezz123/rain-rust-sdk/blob/main/README.md

Pattern match against RainError variants to handle API, HTTP, and authentication errors appropriately.

```rust
use rain_sdk::error::RainError;

match client.get_user_application(&user_id).await {
    Ok(application) => println!("Success: {:?}", application),
    Err(RainError::ApiError { status, response }) => {
        println!("API error (status {}): {}", status, response);
        // Common status codes:
        // - 400: Invalid request
        // - 401: Invalid authorization
        // - 403: Forbidden
        // - 404: Not found
        // - 409: Conflict
        // - 423: Locked
        // - 500: Internal server error
    },
    Err(RainError::HttpError(err)) => println!("HTTP error: {}", err),
    Err(RainError::AuthError(msg)) => println!("Auth error: {}", msg),
    Err(e) => println!("Other error: {}", e),
}
```
